[config] move config of the secret used to encrypt session's data ID in pyramid.ini (closes #11689082)
Introduce a new config entry (in pyramid.ini) for this (cubicweb.session.secret)
to replace the (now deprecated) pyramid-session-secret (in all-in-one.conf).
So we have now 3 secrets to configure:
- cubicweb.session.secret: to encrypt session's data ID stored in a cookie,
- cubicweb.auth.authtkt.session.secret: to encrypt auth cookie
- cubicweb.auth.authtkt.persistent.secret: to encrypt persistent session auth cookie
